MARINATE CHICKEN: Place garlic, cilantro, soy sauce, lime juice, and sesame oil in a food processor and process until smooth.
Place chicken in large zipper-top bag, and pour marinade into bag. Seal the bag, and shake until chicken is coated with marinade. Lay bag flat in refrigerator, and marinate for at least 1 hour, and up to overnight.
COOK CHICKEN: Move oven rack 4 inches from broiler, and preheat broiler. Line rimmed baking sheet with foil, and spray lightly with nonstick cooking spray. Remove chicken from marinade and arrange in a single layer, spacing apart, on prepared baking sheet. Drizzle chicken with 1 tablespoon olive oil, and season with salt and pepper. Broil until browned and cooked through, about 10-14 minutes (all depending on your broiler). Internal temperature of chicken should register 165 degrees F on a meat thermometer. Let chicken rest for 5 minutes before serving. Serve with lime wedges.
